It can be identified as missing tooth structure and may manifest as pits or grooves in the crown of the affected teeth, and in extreme cases, some portions of the crown of the tooth may have no enamel, exposing the dentin. [2] It may be generalized across the dentition or localized to a few teeth. Defects are categorized by shape or location.
Plane-form enamel hypoplasia is a dental condition that is distinguished by defects in the teeth enamel, that can occur due to genetic or environmental factors. It is common for the disease to occur during the developmental stages of the teeth, and childhood illnesses, such as respiratory infections, are often linked to disturbance of the enamel formation [5] [6].
] It is the most common type of enamel hypoplasia reported in clinical and archaeological samples, with other types including plane-form enamel hypoplasia and pitting enamel hypoplasia. [12] Linear enamel hypoplasia can be caused by a variety of factors, from genetic conditions to malnutrition and illnesses during childhood.
One of the most common types, pitting enamel hypoplasia (PEH), ranges from small circular pinpricks to larger irregular depressions. [2] Pits also vary in how they occur on a tooth surface, some forming rows and others more randomly scattered. [ 3 ]
People with amelogenesis imperfecta may have teeth with abnormal color: yellow, brown or grey; this disorder can affect any number of teeth of both dentitions. Enamel hypoplasia manifests in a variety of ways depending on the type of AI an individual has (see below), with pitting and plane-form defects common. [4] The teeth have a higher risk ...
Studies have shown that an increase in exposure to cigarette smoking can increase the risk of tooth loss. In addition, studies have also found that when people stop smoking, there is a decrease in tooth loss. [6] Proper nutrition has been shown to prevent tooth loss by providing the nutrients necessary to maintain enamel strength. [7] Tooth ...
Researchers have proposed that abfraction is caused by forces on the tooth from the teeth touching together, occlusal forces, when chewing and swallowing. [ 4 ] [ 12 ] These lead to a concentration of stress and flexion at the area where the enamel and cementum meet (CEJ).
Enamel hypocalcification is a defect of tooth enamel in which normal amounts of enamel are produced but are hypomineralized. [ 1 ] [ 2 ] In this defect the enamel is softer than normal. Some areas in enamel are hypocalcified: enamel spindles, enamel tufts, and enamel lamellae.
